Abstract

Cette invention concerne un procédé permettant de découper automatiquement des tresses métalliques. Ce procédé consiste à insérer l'un après l'autre deux noyaux métalliques (11, 12) dans une tresse métallique (7) cylindrique et creuse qui est faite d'acier inoxydable. La tresse métallique (7) est ensuite tirée dans des directions opposées entre les deux noyaux métalliques (11, 12), puis découpée entre lesdits noyaux métalliques (11, 12).
